Abstract: 【Abstract】 Objective To explore the clinical effects of positional adjustment unsatisfied sequential cranial remolding orthoses (CRO) and CRO alone treatment in the treatment of infant positional plagiocephaly (PP), in order to optimize treatment strategies. Method A total of 85 infants with PP aged 3 to 7 months treated at the Pediatric Head Correction Clinic of Beijing United Family Hospital from February 2019 to February 2024 were included in the retrospective study. According to the principle of voluntary selection of treatment methods, 56 cases were in the postural adjustment group, of which 18 out of 24 infants with ineffective postural adjustment received CRO treatment; CRO treatment was preferred in 29 cases Measurement of cranial vault asymmetry (CVA), cranial vault asymmetry index (CVAI), anterior symmetry ratio (ASR), and posterior symmetry ratio (PSR) using three-dimensional laser acquisition technology. The improvement rate of CVAI was used as reference data to evaluate the treatment effect of PP. CVAI improvement rate ≥ 10% was defined as effective treatment intervention. Compare the clinical outcomes of two treatment options. Statistical methods performed by t-test, Mann-Whitney U test. Result The effectiveness rate of the positional adjustment treatment group was 57.1% (32/56), with a CVAI improvement rate of [19.0(1.6, 37.9)]%. Among them, 18 patients received sequential CRO treatment, achieving an effectiveness rate of 100% (18/18) and a CVAI improvement rate of [51.5 (38.0, 68.4)]%. The CVAI after sequential CRO treatment was significantly lower than before treatment [(3.0±1.3)% vs (7.0±2.3)%, t=6.248, P<0.001]. The effectiveness rate of the pure CRO treatment group was 100% (29/29), with a CVAI improvement rate of [53.7 (33.4, 67.3)]%, showing no statistically significant difference compared to the sequential CRO treatment group (Z=-0.120, P>0.05). The CVAI after pure CRO treatment was significantly lower than before treatment[(7.5±2.3)% vs (3.5±1.7)%, t=7.191, P<0.001]. The duration of sequential treatment was longer than that ofpure CRO treatment [(5.7±2.2) months vs (3.4±1.5) months, t=4.288, P<0.001]. The duration of CRO use in the sequential treatment group was also longer than in the pure CRO group [(4.4±1.8) months vs (3.4±1.5)months, t= 2.129, P < 0.05]. There were no statistically significant differences in the severity of plagiocephalyor treatment outcomes between the two groups before and after treatment (all P>0.05). Conclusion For infants aged 3 to 7 months with PP, positional adjustment can effectively improve head shape in more than 50% of cases, but its therapeutic effect is not as significant as that of CRO therapy. If positional adjustment yields suboptimal results, sequential CRO therapy achieves similar outcomes to pure CRO therapy. However the duration of pure CRO therapy is shorter than that of sequential therapy.
